North German Plain,lowland region of northern Germany extending from the North and Baltic seas southward to the foreland of the Central German Uplands. It is a portion of the Great European Plain that spreads from the Belgium coast east into the lowlands of central Russia.

Nearly the entire North German Plain lies less than 330 feet (100 m) above sea level. The lowland is drained by the north-flowing Rhine, Ems, Weser, Elbe, and Oder rivers; a network of shipping canals and inland waterways connect the rivers from east to west. Glacial action formed the region’s landform patterns, which can be divided into three major areas of relief from west to east: the alluvial deposits of the Lower Rhineland, the flat glacial sands and gravels of Lower Saxony west of the Elbe River, and the series of morainic uplands and troughs extending eastward from Schleswig-Holstein along the Baltic Sea. The climate is maritime, characterized by cool summers and mild winters, considerable precipitation, and strong northwesterly winds.

While the plain generally lacks mineral resources, some areas, especially those covered by loess (such as portions of the far south), are rich agricultural regions that support a dense population and many towns. Other areas with poor soils are thinly populated. Many of Germany’s great ports—including Bremen, Bremerhaven, Hamburg, Lübeck, and Kiel—are situated along the plain’s dense network of canals and navigable rivers. Attractions in the region’s historic cities and a number of national parks, located along the coast and on the lower Oder River, support an important tourist industry.
